JP 2005-23596 A

  In the conventional seismic control structure described above, considering the high degree of freedom of design so that openings such as windows and doorways can be provided in various ways in the column beam frame of the building unit, A seismic control panel with a width smaller than that of this column-beam frame equipped with a seismic control device was installed in various positions.

  However, in any case, since this seismic control structure is installed by fitting a seismic control panel in the column beam frame of the building unit, the degree of freedom in design is low.

  This seismic control panel is installed in a column beam structure by installing a vibration control device consisting of various dampers between a pair of studs and joining the upper and lower ends of each pair of studs to the ceiling beam and floor beam. Because of this structure, when horizontal external force is input to the building unit at the time of an earthquake, large stresses are concentrated on the joined part of the column between the ceiling beam and floor beam and the upper and lower ends of the column. The ceiling beam and floor beam part to which the joints are bonded are deformed not only in the horizontal direction but also in the vertical direction, and the amount of deformation of the vibration control device is reduced accordingly, and the vibration energy as expected cannot be absorbed. , Couldn't show great seismic control performance.

  In addition, the ceiling beam and floor beam must have large cross sections so that they do not buckle, and the joints at the upper and lower ends of the studs must be reinforced with a stiffener, etc. It was uneconomical.

  Accordingly, an object of the present invention is to provide a damping structure and a building having the damping structure that have a high degree of freedom in design, can exhibit great damping performance, have excellent workability, and can be implemented economically. Yes.

Further, in the portion provided with the gap, between the rigid joints of only the upper of the building units adjacent are connected by a connecting member.

  Further, the vibration control device may be a hydraulic damper, a friction damper, a viscoelastic damper, or a damper that combines these.

  Moreover, the building of this invention is equipped with one of the above-mentioned seismic control structures.

  The seismic control structure of the present invention configured as described above has a structure in which building units are arranged at intervals, and a seismic control device is installed at a portion where the intervals are provided. Since there is no need to install a vibration control panel in the frame, the design is more flexible than in the prior art.

Here, in the portion provided with the gap, since the vibration control device between the lower rigid joint of the upper rigid joint portion and the other building unit of one of the building units are laid obliquely, Vibration Control The amount of deformation of the device is the largest, can absorb the expected vibration energy, and can exert a great vibration control performance. In addition, since the place where the vibration control device is installed is the rigid joint having the greatest strength of the building unit, it is not necessary to reinforce with a stiffener or the like, and the workability is excellent. Furthermore, since the location where stress is concentrated at the time of an earthquake also becomes this rigid joint, it is not necessary to make the ceiling beam and floor beam have a large cross section compared to the prior art, so it can be implemented economically. .

Further, in the portion provided with the gap, since between the upper only of rigid joints of the building units adjacent are connected by a connecting member, when the neighboring building units, it is necessary to transmit the horizontal forces such as wind loads In addition, a horizontal force can be transmitted through this connecting member.

  Furthermore, if the vibration control device is a hydraulic damper, friction damper, viscoelastic damper, or a damper that combines these, there is no need for replacement or adjustment. Excellent and economical.

  Moreover, since the building of this invention comprised in this way becomes the structure provided with one of the above-mentioned seismic control structures, it has a high design freedom, is excellent in workability, and can be implemented economically.

  Further, the rear upper rigid joint G <b> 2 and the rear upper rigid joint G <b> 6 are also coupled by the coupling member 5.

  Further, hydraulic pressure as a vibration control device is interposed between the rigid lower joint G4 of the left building unit 4 and the upper rigid joint G5 of the right building unit 4 via the brace members 6 and 6. The damper 7 is constructed.

  Here, the connecting member 5 only needs to play a role of transmitting a horizontal force such as wind load between the ceiling beams 2 and 2, so that both ends thereof are pinned to the rigid joints G1, G2, G5 and G6. It may be simply joined.

  However, if it is not necessary to transmit a horizontal force such as wind load, the connecting member 5 may not be provided.

  Moreover, although the hydraulic damper 7 was used for the damping device, it is not limited to this, The damper which does not need replacement | exchange or adjustment, such as a friction damper, a viscoelastic damper, or the damper which compounded these, is used suitably. .

Therefore, the amount of deformation of the hydraulic damper 7 is the largest, can absorb the expected vibration energy, and can exhibit a great vibration control performance.

  Further, since the place where the hydraulic damper 7 is installed is the rigid joints G4 and G5 having the highest strength of the building units 4 and 4, there is no need to bother with a stiffener or the like, and the workability is excellent.

  Further, since the location where stress is concentrated during an earthquake is also the rigid joints G4 and G5, the ceiling beams 2,... And the floor beams 3,. Since it is not necessary, it can be implemented economically.

  Moreover, in the part which provided the space | interval, since the rigid joint part G1, G5 of the upper side of adjacent building units 4 and 4 and G2 and G6 are connected by the connection members 5 and 5, the adjacent building units 4 and 4 are connected. When 4 needs to transmit a horizontal force such as a wind load, the horizontal force can be transmitted via the connecting members 5 and 5.

  Furthermore, since the vibration control device is the hydraulic damper 7, there is no need for replacement or adjustment, and it can cope with the continuous occurrence of earthquakes, and is excellent in practicality and economical.
